I guess my pool game isn't good/bad enough to warrant a nickname to this point, but while on the subject it reminded me of a story...
I'm a pretty good golfer and in my younger days, I was in the Army and my Colonel used to pay for my entry fees to play on his scramble teams for tourneys. We were Army guys stationed on an Air Force Base, so the rivalry was pretty intense and my Colonel LOVED to win "their" (<---the AF guys) tournaments and would talk irrational amounts of sh!t when we did since there were only a handful of us and an entire base full of those guys.
Well, the other 2 guys in our group were the Sergeant Major and the XO and my Colonel used to always call my Sergeant Major "foursome" all of the time. The Sergeant Major was a very good golfer, too, and I just assumed it was some kind of endearing private joke they had together. The Sergeant Major never seemed to mind it, and almost acted like it was a badge of honor.
So, one day when it was just me and the Colonel playing (at least a year since I first heard him use the term), I finally asked the Colonel why he called him that. He laughed and said, "because the guy takes FOREVER to hit the ball!...He is like a one man foursome" I asked him why the Sergeant Major didn't seem to mind the fact that he called him that all the time and he said, "it took him 6 months to even ask me why I called him that and once he did, I told him because he was the "heart" of our group."
Poor guy never even knew. And it was true, too. Slowest guy EVER w/all his ticks, waggling, etc. Didn't surprise me that it took so long for him to question it either. Guy was right out of central casting as the strong, silent, Sergeant Major. Think Sam Elliot in "We Were Soldiers."
